. A plication filed November 2, 1806. Serial No. 285,578.

To all whom it "tag concern:

.Be it known that LEDWARD Y. Moonn, a

citizen of the United States, residing at Cleveland, in the county ofOuyahoga and State of cable and furnish means for graspingand holdingthe load. It is especially designed for use with an ammunition-hoist,bein' so formed that it may conveniently grasp a s ell as it lies in itscase and securely hold it The grappling-arms are swiveled' to thesupporting-block, which allows the load to be turned as desired. Thearms are so formed that the weight of the load prevents them fromprematurely releasing the load, while a clam is provided to prevent-theload shifting endw'ise. These features are hereinafter more ,fullydescribed, and summarized in the claims.

In the drawings, Figure 1 is a pers ective view of m grap le su portedby 9. ca lo and showing t e 10a in p ace. Fig. 2,is an end view of aple. Fig.3 isacross-section arallel wit Fig. 2. Fig. 4 is a lan view.ig. 5 is a cross-section through t e swivel at right angles to Fig. 3.

Referring to the parts by letters, A represents a supporting-bar, whichcarries near each end a sheave B.- The; bar is formed with ends a, whichproject backward, so as to leave recesses in which the wheels aremounted, the wheels being journaled on ins G, extending through the endsa and t e body of thebalr. Thesup orting-cable(designatedF) passesdownwar under one of the wheels B and then upward across a groove (1' inthe both reaches thereof.

the inner faces 0 bar and then downward beneath the other wheel B andupward, as shown. The two ends of the cable are intended to besimultaneously elevated; but the sheave-and-groove arrangement isprovided to allow the cable to shift when necessary, equalizing thestrain on G and H represent the two arms of the grapple. Each'of thesearms forms ap roximatel a semicylinder. The arm G is ifurby anare-shaped opening which the 6n the edges of thearm are projecting ribsh, which take into "corresponding grooves formed by the two sides 9 g ofthe arm a G. This allows the. arms to be telescoped one within theother, as shown in Fi or extended, asshown in Figs. 1, 3, an 4. A

bar J is secured at its ends-to the free ends of the side members 9,extending intermediately across the arm H, the other endof the arm Ghaving the integral cross portion g*. This makes, a strong and secureconstruction.

The supporting-bar A is swivele'd to the intermediate arm H by means ofa member K, which is shown as a sleeve mounted in the I arm H and having.a head In on its underside occupying a recess in that arm, while abovethe arm it is j ournaled in the supporting-bar.

Above the su(pporting-b ar isa nut L, which serves to hol the members toether. The

' stud is internally screw-.threade and screw- .low the arms of thegrapple to'pass most convenientl into this s ace and move around theshel I bevel'o the lower ends of the arms on their outer sides, as shownat g and it". When this apple is laced over the shell andone of t e armspul ed out from the other; the grapple will passaround the shell farenou h to support it, so that the elevation of the ca le will-raise theshell.

The weight of the shell acts downwardlyand outwardly on the "curvedarms, which prevents any movement of the one into the other. The loadmay ,then be thus, raised to any desired oint' and is easily released bysimply allowing itto be sup orted on something, taking the weight off te grapple. To prevent the shell shifting longitudina lyin the apple, theclamping-screw N is provided. The ends of the bar A are bent out ofalinement, asshown, to enable the cableto pass directly over the groove(1, which is far enough at the side to be out of the way of the head ofthe clamping-screw' Having thus described my lIIVGDtiOII I claimw 1. Agrapple comprising a pair of arcshaped arms slidably connected vandhaving free ends, whereby the arms may be extend-' ed toembrace morethan a semicircle or telescopedto occupy substantially a semicircle,- ansupporting means on the convex side of said arms.

2. A grapple comprising an arc=shaped arm having "a pair of parallelside members,-

other and having isconnecting ends adapt-.

ed to be spread thereby,.and a'supportingebar swiveled to one, of saidarms near its lnner end.

, 5. In aigrapple, the combination of anarcshaped arm, a bar swiveledthereto, asecond arc-shaped. arm. bifurcated and extending ontoopposite. sides of the first arm and ribs and grooves on thecooperatingedges-of said arms. 7

(LA grapple comprising a bifurcated arc- I shaped arm, a secondarc-shaped arm guided in an arc in said bifurcation, a supportingbarswiveled to-said lastrmentioned arm', and equalizing-sheaves:-carriedbysaid bar.

7 A grapple com rising a biturcatedarcshaped arm, a seconiarc-shapedarm-guided in an arc in said bifurcation, a supportingbar swiveled .tosaid last-mentionedarm and a clamping screw screwing through the swivel.

8. In a grapple,-the combination of abifurcated arm, an intermediate armextending into the bifurcation thereof, ribsand-grooves on thecooperative edgesof said arms, a stud mounted inthe intermediate arm, asupporterases ing-bar above the intermediate arm in which said stud isalso mounted, saidstud being internally screw-threaded, and aclampingscrew occupying such internal screw-thread I and adapted toproject below the intermediate arm and having a head above thesupporting-bar.

r 9. A grapple comprising a pair of cooperating arms, a supporting-barswiveled thereto, an equalizing-sheave carried near each end of the bar,and a support for the flexible elevating member carried, by the barinter- .mediate of said sheaves, said support being at one side of theswivel and the sheaves being set at an angle to allow such flexiblememberto pass directly onto said support.-

. 10. A grapple,jcomprising a pair of arms adapted to telescope withreference to each other and having disconnected ends made to approach orrecede from each other by reason of such telescoping, andasupporting-bar swiveled substantially on a vert cal axisto one of-saidarms.

. -11. A grapple, comprising a pair of areshaped arms adapted totelescope with reference'to each other and having disconnected endsapproaching or receding from each other by reason of such telescoping,and a radial clamping-screw carried by one of said arms.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
